Robin Reilley <br /> Page 2 of 4 <br /> 9/10/2019 <br /> A subset of the collected images from both the"Lower"and "Higher" data sets were processed so as to focus on the <br /> area of interest. <br /> All figures are exported directly from Global Mapper,with the data projected in UTM Zone 13N, using the NAD83 <br /> datum <br /> Figure 1 shows the 2D orthoimage with a green polygon representing the approximate boundary of the reclaimed <br /> strip-pit,and pink polygons representing areas of cheat grass—these are projections of the kmz files you shared <br /> with me). <br /> Figure 2 shows the same data, but zoomed to the extent of the cheat grass polygons. <br /> Based on my experiences from this project, in future I would choose a "Double Grid"type of mission,which is <br /> recommended for 3D models,even though your interest was just in a 2D orthoimage, I'd also change the camera <br /> angle to N70°; 1 think that the improved coverage and overlap,together with the slightly oblique imagery would <br /> improve the quality of the processed data. I would also invest more time up front to characterize the survey area <br /> more precisely. <br /> Specifically,for this project, I would attempt to fly it earlier in the year so as to capture data at a time when the color <br /> of cheat grass is more distinct in comparison to surrounding vegetation. <br /> Anyone may view the files using the following link, (the project folder contains both the raw images and several <br /> georeferenced orthoimages): <br /> https://drive.google.com/drive/folders/1ZKU FL9lf4DgWgPznm8AVylGcT9RDOO4T?usp=sharing <br /> I would appreciate any feedback or comments you have on this project. <br />
